Would that work, or more on which side? Preds get a replacement for Suter, a decent 2nd-3rd line winger and a top D prospect that is NHL ready. Pens get a young center/winger and a very good center prospect. My other highdea was:

Pens trade Morrow, Lovejoy and Kennedy
Bruins trade Horton

That one is interesting. Bruins get 2 depth players (which isn't bad) and a top D prospect that will replace Chara once he retires (and make a nasty pair with Hamilton, IMO). They also get some much needed salary cap relief. Pens get a younger winger for Crosby.
